Chemists create 'Superbowl' molecule; May lead to better health
...one knows yet when this experimental molecule will actually
enter the consumer market, but any useful application is likely to take five to ten years, the researcher estimates. Administration of the molecule for drug delivery could be by mouth or by injection, he adds. There are hurdles to overcome. The curr...
Scientists ID molecular 'switch' in liver that triggers harmful effects of saturated and trans fats

destroy ice shelves. In this case it's possible that a preceding warm period may have primed the ice shelf to disintegrate when the ocean currents shifted.' The scientists analysed sediments from the bottom of a freshwater lake close to the edge of ...

begins changing the dead, foreign bone splint, into the body's own, whole, living bone." Such a transformation can occur because mammals use their skeletons for both support and as a kind of "calcium bank." If calcium, which is necessary for such im...
